Application filed January Myinvention relates to heating and more specifically to an improved radiant heater employing an actual source of radiant heat, and a substantially independent apparent 5. source of heat simulating in appearance an ordinary grate fire, I "Among the Objects of. the. inventionamay be enumerated: i

First, to provide an illuminated apparent source of heat and an actual radiant source substantially independent of the apparent source.

Second, todeliver the-heat ofthenctual source substantially Without heating the .apparent source. 1 c

Third, to obtain a relatively instantaneous supply of heat apparently coming'from a heat source of large mass. 1 1

Fourth, to, provide I an apparent source with reflector means for. localizing the. illuminationto improve theillusion. Y Fifth, to simulate theg illuminat-ion produced by an ordinary grate fire on-the floor OI'fSUPPOIlJlIlg structure. Sixth,to utilize the heat absorbed by the reflecting surface-of the radiant heater efii- ,ciently. v I H Seventh, to provide for symmetrical distribution of heat from one, twoor three heat units at the Will of the user. Further objects and advantages of. the invention will becomeiapparent as the description proceeds. 'f v 1 Intheaccompanying drayvings:

Side plates 18 carrylugsi22 at their rear edges for suitable attachment to Fig. 6 is a section similar toFig- 3shovve, 1925. Serial m. 1,435

the rear panel 26, which panel has-feetEZS extending down to the plane of feet 30. on posts 10 to provide a; four point-support for .theentire. frame. Ornamental-vases or fini- .a ls- 29 are preferably positioned :at the upperends of posts 10,,a1idthe upper-,corners of therear panel, "the central portion of which panel may also preferablybe-v deco- ,rated bysuitablescroll work-31.

.Bottom plate 32 is supported in: any su-itable-"or. preferred Way, as.- on grille, 12 :and

end plates 18, or it-=may ibe-formedrintegral with the end plates. It carries means fer illuminating the lower or apparent "heat source such as a pair ofspaced-fsockets34 equipped with ordinary lightybulbs- 36. In lateral alignment with lights 36-.I prefer: to form a plurality of slots 38 through which "the light from the: bulbs will: shineonrthe floor supporting thest-ructure in euchfa-Way as to illuminate apatternsimilarto-that'il- V luminated by an ordinary grate 'flrevshi-ni ng through thegrate bars. l I 1 A coarse mesh -W-1re-fscreen extends up- Wardly as at39; spacediback of grate:ba.1's-- .as to materially yimprove the 1: lifelike asappearance of the whole. ,tTheseiprojections Will also? carry the-flicker down-" in the front of the; grate as Well 'as at th'e'top.

H To 1 further; increase othe -accuracy "of Z the imitation I provide a reflector 4L8? ofz'si'uitable wmaterial such as'polisheditin. By varying the curvature "of this reflector a: number of different I pleasing effects. may-be =Tobt-ained. Thus thereflectorof Fig. 3 'dircts most. of f the light toward the upper .portion rof" the imitation pile of coals, Whereasreflector T50 of Fig. 6 will 'locate "the apparentacenterwf the'firfle lower and farther forward, the (upper rear edge of the refiector being suitably attached to the lowerr-flange-of-an uppnre- I =f1ector'--52,f preferably ofrpoli'shed' coppenithe sockets 58 for the side heaters.

rear edge of the screen being also attached at this point. Above this point I position the actual source of radiant heat, comprising a central heater 54 and side heaters 56 detachably mounted like ordinary incandescent electric lights in sockets 58. The wiring for energizing the sockets is preferably enclosed in a vertical, tube 60 extending up the back of the rear panel and lateral, tubular shields 62 terminating in end boxes 64 housing the It will be obvious that, if desired, more than one such heater could be mounted on the, central panel. As the, heaters may be inserted in sockets 58 by simplyscrewing them in place,

the user may remove one or more ofthe same when they'are cold. Alternatively the units'can .be made up with only the number desired by the purchaser. A three stage switch 65 maybe. provided for convenient controlin-service. It should be noted that 1 either the central heat unit by itself, the

wing units together, or all three unitstogether, will in each instance deliver a sym metrical heat effect.

ment of Fig. 3 it extends vertically up to the central socket 58' and then curves for-,

ward and down again to form a dome 68 over the end units. By varying slightly the positioning and curvatures of the reflector a considerable variation in the distribution of heat can be obtained. Thus the shape shown in Fig. 3 will direct the bulk of the heat very close to the front of the device,

a-considerable portion of it impinging in;

the first instance on the imitationcoal bed 42. 'The arrangement below the heater in both Figs. 5 and 6 will direct a much larger portion ofthe radiation from theheater by a single reflection outinto the room in; front of the'fire place. ,The dome 7 0 of Fig 6 V will distribute-its reflected heat more or less uniformly, some of itbeing reflected down into the imitationgr'ate and a considerable portion being reflected back to the reflector below the heaterand then out into the room, whereas'the dome of Fig. 5 will still further shift. the distribution away from the "grate,

.the' rear'portion"72 reflecting directly in front of the grate'and the front portion. 74

Jreflecting almost entirely back to the lower portion 7 6; r

"The bestreflecting surfaces that can be obtained for the radiant heat will absorb a material fraction of the heat impinging on L-them, and even the lower light-reflecting screens 48 and will be slightly'warm'ed.

To deliver as much as'possible of this heat in a. convenient, usable form,the space at 7 8 11s provided, continued by the clearance at between the dome 68 and the forwardly arched portion, 82 of the rear panel.

l1ood184. extends outwardly and downwardly 5 over the strongly heated dome 68 and down under the front edge of the hood 84, *where it affords a very pleasant means of warming ones hands. Incidentally the circulation thus set up keeps the reflecting screenat a somewhat lower temperature, and materially improves the efllciency' of the heat transfer from the heat unit tolthe room and its contents.

Without further elaboration, the foregoing will so fully explain the gist of my 'invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service without eliminating certain features which may properly be said to constitute the essential items'of novelty involved, which itemsare intended to be defined andsecured tomeby the following claims. 7 '-Iclaim:'- 7 c y 1. A fire place unit, comprising an illuminated imitation grate, a source of radiant heat above said grate, a continuously curved reflector below said source set to reflect-radiant-heat out over the top of saidgrate, a

' reflecting hood above said source,said hood comprising afirst 1 portion adjacent the source set to reflect directly out over said grate and a second portion remote from said source set to reflect back onto/thereflector below 'saidsource, and a-secondhoodspaced over said first hood to define an air passage. 7 V l '2.

Y

3;'Afireplace unit comprising a radiant source, a first reflector means for reflecting;

some of the radiation from saidsource directly into the spaceto'be heated, and a second reflector means for reflecting other vportions ofsaidradia'tion twice'to deliver them 'to the same space, said secondrefle ctor means including portions of said first reflector means. 1

4. A fireplace unit, comprising a radiant source, a first reflector means for reflecting some of the radiation from said source directly into the space to be heated, and a second reflector means for reflecting other portions of said radiation twice to deliver them to the same space.

5. A fireplace unit comprising a light source, a heat source above said light source, a reflector behind each source, said reflectors curving forward between said sources a fo- I raminated support extending infront of and above said light source, and means for a reflector behind each source, and a reflector above said heat source shaped to throw av substantial radiation from said heat source and a substantial illumination from said light source down and back onto the reflector behind said heat source.

In witness whereof, I hereunto subscribe my name this 5th day of January, 1925.
